The documentation for
If dst_name already exists at the location dst_loc_id, H5Ocopy will fail.
I find it limiting. In particular, I’d like to export a subset of HDF5
dataset into a separate file, efficiently copying the group subitems and
attributes info another HDF5 file’s root. Although it’s in theory
possible to implement on my side, wouldn’t it be great if that was
handled at HDF5 library level?
Any chance this limitation is someday relieved?
